Description

NM_133259.3(LRPPRC):c.1277T>A(L426*) is expected to be pathogenic in the context of Leigh syndrome, French-Canadian type. This variant is predicted to lead to an abnormal or absent protein product due to the creation of a premature termination codon in LRPPRC, a gene where loss-of-function variants are known to be pathogenic. Please note: this variant was assessed in the context of healthy population screening.
